060d982036 Combine the ambient and spot alphas into the base color

is color space invariant.
Also includes cleanup in SampleAndroidShadows.

Changes the Android shadow sample to use stroked roundrects when
we can (mainly if stroked geometry area < fill geometry area).

Also changes the setup for the overstroke geometry so that it computes
the correct distance to the outer edge.
